Shear design of reinforced and prestressed concrete beams based on a mechanical model
(International Federation for Structural Concrete (fib), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialDifferent resisting actions interact in the shear resistance of cracked concrete beams whose relative importance varies along loading as damage evolves. Thus, it is not possible to establish a governing resisting action ... -
Simulations of fracture in concrete beams under bending using a continuum and discrete approach
(CIMNE, 2015)
Comunicació de congrés
Accés obertThe paper describes two-dimensional meso-scale results of fracture in notched concrete beams under bending. Concrete was modelled as a random heterogeneous 4-phase material composed of aggregate particles, cement matrix, ... -
The fracture testing of ductile polymer films: Effect of the specimen notching
(Elsevier, 2017-10-01)
Article
Accés obertThe fracture of a ductile polymer film, a heterophase ethylene-propylene block copolymer, has been studied, combining a range of characterisation methods in an attempt to provide a better understanding of the intricate ... -
Three-dimensional simulation of crack propagation in ferroelectric polycrystals: Effect of combined toughening mechanisms
(2014-02-15)
Article
Accés restringit per política de l'editorialWe simulate the fracture processes of ferroelectric polycrystals in three dimensions using a phase-field model. In this model, the grain boundaries, cracks and ferroelectric domain walls are represented in a diffuse way ...
